COLOSSAL means something of great power, such as high mountains, dramatic skies, volcanic explosions, giant trees, huge ocean waves, or large architectural structures.  It could also be more personal, such as something that impacted you in significant ways.  I chose an image of Philadelphia's 30th Street Station (railroad) colossal pillars.  Long ago I'd drive my husband to this station every morning for his daily commute.  It seemed trivial, but this routine had an incredible impact in our lives.

Think of something colossal in your life.  It may include you, parts of you, or of significance to you.  Be sure to capture your imagine in low key style, with more shadows than light but revealing key details.  A good starting point for your camera settings include low ISO, low f-stop and fast shutter speed.

I can't wait to see what's colossal in your life.  Have fun!
